Your typing rhythm is a fingerprint.

This demo runs against Clean Lava's live scoring engine. Teach it how you type in three short rounds — then watch it verify you. Hand the device to someone else and it should notice.

// What you type never leaves this page. Only rhythm statistics are sent — session timing summaries plus per-key timing averages under opaque labels, never content — and every score returned carries differential-privacy noise.

Now try to fool it. Hand this device to a friend and have them type the same sentence — or type it yourself in a deliberately different style (one finger, other hand, much faster). A different rhythm should push the verdict to STEP_UP or BLOCK. That step-up is exactly what a bank would trigger before a high-value transfer.
